Conus xenicus           (Pilsbry & Johnson, 1917)

Description (1):

The shell is broad above, the diameter about two-thirds of the length; spire low, its outline strongly concave, rising to an acute apex; periphery carinate, the slopes below it nearly straight. The  early whorls have a smooth keel, projecting above the suture, but the last five are flat, with very weak traces of spiral striae, and separated by a plain, narrowly impressed suture. The last whorl has  coarse, well separated spiral cords on the anterior end, but under suitably oblique light very faint spirals may be seen throughout. 

The faint growth-striae retract rather strongly near the shoulder. The aperture is very narrow. 

Length 29 mm., diam. 19 mm. (type). 

Length 27 mm., diam. 17  mm.

Besides the type, No. 2575, A. N. S. P., there are three other 
specimens in the lot. It was labeled "Conus sp. ?, monstrosity" by Gabb, but none of the specimens shows any trace of injury, and we have every reason to believe that they are entirely normal.
